The waste incinerator burns a certain amount of fuel, and the required amount of oxygen is determined. If the oxygen content in the flue gas is too high, it means that there is too much air supplied, and the extra air will also rise to a very high temperature. In this way, it will take away part of the heat and reduce the effective use of fuel.
At the same time, these excess air is blown in by the blower, which also consumes more power of the blower. Of course, it is also discharged with the induced draft fan, which also consumes more power of the induced draft fan. However, if the oxygen content in the flue gas is too low, the fuel will not be fully burned.

-What are the hidden dangers caused by high oxygen content in flue gas?
1. Excessive air will take away a lot of physical heat, causing unnecessary waste;
2. The furnace temperature is reduced, the fuel consumption is increased, and the physical incomplete combustion heat loss is also caused;
3. Increase power consumption and mechanical wear;
4. The oxygen content of the exhaust gas is too high, and the concentration of nitrogen oxides in the exhaust gas is too high. However, if the oxygen content in the flue gas is too low, the fuel will not be fully burned.
 
-What system is used for oxygen control?
The oxygen content in the furnace is closely related to the ignition, combustion and burnout of the garbage in the incinerator, which in turn affects the output of the waste heat boiler and the operating parameters such as pollutant discharge. Wuhan Huamin's HM-OSZ high temperature in-line zirconia oxygen content analysis system is used to monitor directly in the high temperature area. Through continuous online detection of oxygen content in the furnace, the air-fuel ratio of each area can be reasonably adjusted and the combustion efficiency can be improved. Economical choice for long-term in-line measurements in high temperature zones in incinerators.

The adjustment of the oxygen content in the incinerator directly affects the ignition, combustion and burnout of the garbage. The HM-OSZ high temperature in-line zirconia oxygen content analysis system of Wuhan Huamin is used to adjust the oxygen content in the furnace to realize the high efficiency and environmental protection of the incinerator. and provide important technical support for safe operation.
